As I have noted in other discussions, I prefer Coleman hoses. I had an off-brand.. no idea who made it... that caused two fires in my cooking equipment. With the first one I assumed I had made a poor connection. I replaced it with a Coleman hose after the second event and never had another problem. I never cooked in the galley, always on a separate table.
Does anyone make use of the old style propane tanks? I am guessing they can be retro fitted with a current connector. I have one with a very tall "collar" that came off my 1960 trailer.
